A man walked by. Despite the morning rush, he stepped aside unhesitatingly, fished his pockets for coins and dropped them into the bag. Strangely, instead of returning to the crowd, he took the sign, turned it around, and wrote something else. He then handed back the sign with the new words to the blind girl.
Soon the hat began to fill up. A lot more people were giving money to the blind girl. At the end of the day, the man who had changed the sign came to see how things were keeping up with the girl he encountered earlier that morning. The girl recognized his footsteps and asked, "Were you the one who changed my sign this morning? What did you write?"
The man said, "I only wrote the truth. I said what you said but in a different way."
What he had written was: "Today is a beautiful day and I cannot see it."
The first sign merely stated that the girl is blind. The second sign told people they were so lucky that they were not blind and presented them with many more reasons to search within themselves for the things that they should be grateful to God for.
Don't put off gratitude, for the time to express it may not be ample.
